Don't worry, oblation fan. You'll get there eventually.
Meld could never work as a keyword. It's incredibly complex. Keeping track of abilities gained cannot appear on too many cards in a set, or at any rarity other than rare (or mythic). Besides, meld is pretty much exclusively a blue ability. To be a keyword, meld has to be vague, using phrases like "permanent that shares a card type." This means that it cannot, in its current form, even be used as a one-of ability on a rare card in a set. However, this version can:
Whenever a creature comes into play, CARDNAME becomes a copy of that creature and gains this ability.
So why don't I use that for meld? Because meld is too riddled with problems for me to put that much effort into fixing it. Because it doesn't work with legendary permanents. And because of this:
What do you do when your creature is equipped with something that suddenly stops being an equipment? Or is enchanted with something that suddenly stops being an aura? I have no idea. Changeling Blade has to keep its old abilities, so it needs the wordy version of meld.
All meld cards are essentially the same. The only thing that varies is their card type. Meld is a cool idea, but a flawed and narrow mechanic. We won't be spending a second day on it.
